We can draw an analogy between the proposed sinusoidal functions for PE and alternating bits in a six bit long binary number, as shown in Figure REF  [1]}, [2]}. In the binary format, the least significant bit (shown in the orange color) alternates with the highest frequency. Moving to the left (indigo), the frequency of bit oscillation between 0 and 1, decreases. Similarly, in the sinusoidal PE, as we move along the positional encoding vector, the frequency of the sinusoidal function changes.
